Always Game

Our highly capable aluminum gravel bike. Built for chasing horizons, exploring routes less travelled or accelerating your commute.

Model Description

The premium 1x drop-bar build in the Topstone CAAD lineup. Topstone CAAD 1 GRX 1x pairs a premium aluminum frame with a carbon fork, smart mounts, Shimano GRX 610 1x12 shifting, WTB i25 wheels with Vulpine 45 tires, and a clean Conceal cockpit for a ride that feels fast, capable, and dialed from the first pedal stroke. Built for gravel riders who like a clean drivetrain, quick response, and fewer moving parts when the road turns to dirt, broken pavement, and whatever gets added to the day.

What it's for

Fast gravel, adventure rides, mixed surfaces, all-day exploration

Highlights

  • Premium SmartForm C1 aluminum frame, backed by our Lifetime Warranty
  • Shimano GRX 610 1x12 drivetrain delivers clean shifting and gravel-ready simplicity
  • Full carbon fork reduces weight and adds comfort and capability
  • WTB ST i25 wheels and WTB Vulpine 700x45c tires balance efficiency and grip
  • Cannondale Conceal stem provides a clean, integrated cockpit
  • Up to 52mm measured tire clearance in the frame and 56mm in the fork





















Always Game

Smoother Ride, Swifter Pace

Smoother Ride, Swifter Pace

With room for wide 52mm tires, a comfort-focused frame design, and OutFront Steering, Topstone CAAD gives riders more confidence when the surface turns loose, broken, or chattery. Bigger tires add grip and comfort, while the geometry helps the bike hold its line without feeling dull. Add Lefty Oliver on selected models, and the front end gains even more control.

Carry More Than Speed

Carry More Than Speed

Designed to move and built to carry, Topstone CAAD gives riders mounts across the frame and fork for bottles, bags, fenders, racks, lights, and the good ideas that need hardware. Flush top tube bosses leave the frame clean when the gear comes off, while rack, fender, kickstand, and dynamo compatibility open up more ways to ride.

Tested For Real Use

Tested For Real Use

Topstone CAAD is made for riders who actually use their bikes. Loaded rides, wet commutes, dusty backroads, repeat. We test it hard, refine it, and back it with a lifetime warranty because confidence should come standard. Light, tough, and ready for repeat days on road, dirt, and everything between.

Easy To Live With

Easy To Live With

Topstone CAAD is built around practical standards that make ownership simpler. A BSA threaded bottom bracket, UDH, standard thru-axles, 27.2mm seatpost, standard steerer compatibility, and clean internal routing all make the bike easier to service, adjust, and set up your way. Less hassle, more ride time.
